In this episode of pplpod, we explore the life of General James Wilkinson, the highest-ranking officer in the United States Army, who spent decades as a paid Spanish agent while serving the country he betrayed. Born in 1757 in Maryland to a family that had lost its fortune, he was a second son who inherited no land but kept an aristocratic sense of entitlement, sharpened by his father's dying demand that he never tolerate an insult. He studied medicine at the University of Pennsylvania before the Revolutionary War offered a faster route to status. Joining the Continental Army in 1775, he served as an aide to Nathanael Greene, Benedict Arnold, and Horatio Gates, and his slow delivery and embellished account of the victory at Saratoga earned him a brevet promotion to brigadier general at age 20.
The episode follows his role in the Conway Cabal, his forced resignation in 1778, and his marriage to Anne Biddle. He moved to Kentucky in 1784 and traveled to New Orleans in 1787, where he swore allegiance to Spain, wrote the First Memorial, and became Agent 13 on a secret pension. He later undermined Anthony Wayne, whose death in 1796 ended a looming court martial. Wilkinson became senior officer of the army, served as the first governor of the Louisiana Territory, and betrayed Aaron Burr by altering the cipher letter. Defeats at Chrysler's Farm and Lacolle Mills ended his career in 1815, and he died in Mexico in 1825. In 1854 historian Charles Gayarre found the Spanish records of his payments, leaving a legacy of deception, ambition, and exposed betrayal.
